Improvement in sash-holder



Letters Patent No. 87 ,683, dated lila/rch,` 9, 1869.

-oom IMPROVEMENT IN SASH-HOLDER TheSchedule referred to in these Letters Patent and making part of the sume.

To all whom it A'may concern:

Be it known that I, DANIEL P. LAGEY, of Orford-y ville, in the county of Rock, and State of Wisconsin, have invented. certain new and useful Improvements in Sash-Locks; andI do hereby declare that the following is a-full, clear, and exact-description thereof', reference being had to the accompanying drawings, andto the letters of reference marked thereon, which form a part of this specification, in which- Figure 1 represents a front view of my sash and window-frame.

Figure 2 gives an elevation of the inner surface of one side-of window-frame, with` the strip removed, so as to aiford a view of the latches. A

Figure 3 represents a spring, with its shank inserted in the window-frame.

Figure 4 is a plan view of the latch that locks the lower sash.

Figure 5 is a plan view of the latch that locks the uppersash. Figure 6 is a side view of the spring exhibited in Figure 7 is a section of the strip which confines the latches in place.

rIhe nature of my invention consists in' the arrangement of two latches and a spring, for locking the upper and lower sashes of a window, and also to prevent them fr lom rattling, .the said latches and spring being constructed and operated inthe manner substantially as hereinafter set forth.

A represents the window-frame, furnished with sashframes B and B.

y O O, in fig. 2, represent the grooves made to receive the sash-frames B and B.

d designates a latch, secured to the inner surface of frame A by a screw, on which said latch is allowed to play freely.

On the onter surface of latch d is the catch or stop e, the -use of which will be hereinafter seen.

. g represents a metal rod, fastened to latch d at right angles with the said latch. By this ,rd the latch dis operated.

h, represents a spiral spring, the upper end of which presses against the latch d, while its .lower end is coiled around a screw.

f represents a second latch, conned to the windowf frame in the same manner as latch d, and furnished with a catch or stop, fi, and rod or handle, j, also with?.

a spiral spring, 7c, which is conned in its place by the same means, and for the same purpose as spring h, already described.

Near thelower end of the upper sash-frame, a depression is made, to receive the catch c', and midway of the lower sash-frame, a similar depression is made, to receive the catch e.

m designates a spring, with a shank extending at right angles with it, 'the said shank being secured to frame A.

The spring mis curved in such a manner that lts concave side will lap over the strip that separates the two sash-frames, while the convex side will press against the top of the lower sash-frame, and keep it from rattling under the influence of wind or other causes.

'In operating latch f, the rod 7' must be 'rnoyed upward to the top of the slots in strip R. 'IhisTnov-e-` ment will disengage the catch i from the depression 1n which it was embedded, and place the frame in condition to be taken out.

In raising the lower sash, the same upward motion of rod g will free the latch d, so that the sash can be raised, and stopped at any required elevation, by letting go the rod g, and allowing thecatch to press on the surface of the sash-frame.

The chief advantage I claim for my mode ofloclring4 window-sash in the manner above described is, that it `s impossible to remove the upper, sash, or raise the A lower one, from the outside. I am aware that latches of similar character are in use, and I do not claim such latches of themselves, nor the principle of their operation; neither do I claim the combination of such latches with a window-sash; but

. What I do claim, is

The latches d f, in conjunction with the lower and upper sashes of a window, as constructed and arranged, as and for the purpose set forth.

In testimony that I claim the foregoing as my own, I aflxmy signature, 'inpresenee of two witnesses.`

DANIEL P. LACEY. Witnesses:
